SP10114 RMTLAND - Remoteland
Description
In the Republic of Remoteland, the people celebrate their independence day every year. However, as it was a long long time ago, nobody can remember when it was exactly. The only thing people can remember is that today, the number of days elapsed since their independence $D$ is a perfect square, and moreover it is the largest possible such number one can form as a product of distinct numbers less than or equal to $n$.
As the years in Remoteland have $1,000,000,007$ days, their citizens just need $D$ modulo $1,000,000,007$. Note that they are interested in the largest $D$, not in the largest $D$ modulo $1,000,000,007$.
Input Format
Every test case is described by a single line with an integer n. ( $1 \le n \le 10^7$ )
Output Format
For each test case, output the number of days ago the Republic became independent, modulo $1,000,000,007$, one per line.
